The colour which deviates most in the formation of spectrum of white light by a prism isa)Greenb)Yellowc)Redd)VioletCorrect answer is option 'D'. Can you explain this answer?

Question

Answer

When white light falls on a glass prism, each colour in it is refracted by a different angle, from which red colour is least deviated and violet most.

Answer

Since violet color has shorter wavelength so it deviats most

Answer

Because after refraction different colours bend at different angle due to varying wavelength.since violet has shorter wavelength that's y violet colour is deviated most in the formation of spectrum..

Answer

Answer

Explanation:
When white light passes through a prism, it gets refracted and splits into its constituent colors, forming a spectrum. This phenomenon is called dispersion. The colors in the spectrum are arranged in a specific order, with red being the least deviated and violet being the most deviated.

Prism and Dispersion:
- A prism is a transparent optical element with at least two flat surfaces that refract light.
- When white light enters a prism, it bends or refracts as it passes through the prism due to the change in speed.
- The bending of light causes the different colors in white light to separate and form a spectrum.
- This separation of colors is due to the phenomenon of dispersion, where different colors of light have different wavelengths and hence different speeds and angles of refraction.

Order of Colors in the Spectrum:
- When white light passes through a prism, it splits into a spectrum of colors in a specific order.
- The colors in the spectrum are arranged in the following order: red, orange, yellow, green, blue, indigo, and violet (ROYGBIV).
- This order is determined by the wavelength of each color, with red having the longest wavelength and violet having the shortest wavelength.

Deviation of Colors:
- The amount of deviation or bending of each color in the spectrum depends on its wavelength.
- Colors with longer wavelengths, such as red, are less deviated or bent compared to colors with shorter wavelengths, such as violet.
- Therefore, the color that deviates the most in the formation of the spectrum of white light by a prism is violet.

Conclusion:
In summary, the color that deviates the most in the formation of the spectrum of white light by a prism is violet. This is due to the shorter wavelength of violet light compared to other colors, resulting in a higher degree of refraction or bending when passing through a prism.
